Where is the 2003 Mustang cabin air filter located?

If you’re like me and can’t find the cabin air filter on your 2003 Mustang, don’t stress! Turns out, they didn’t put one in until later models. Yeah, crazy, right? If your AC is smelling funky, it’s not the filter—it’s probably time to clean out the vents or replace the blower motor.
